ABSTRACT

Compositions for oxidation dyeing keratin fibers, such as human keratin fibers like hair, comprising, in a dyeing medium, (1) at least one oxidation dye, and (2) a combination comprising at least one cyclohomopolymer of dialkyldiallylammonium and at least one other particular quaternary polyammonium. Processes comprising such oxidation dyeing compositions.

The present invention relates to cosmetic compositions for oxidation dyeing keratin fibers, such as human keratin fibers like hair, comprising, in a dyeing medium, (1) at least one oxidation dye, and (2) a combination comprising at least one cyclohomopolymer of dialkyldiallylammonium and at least one other particular quaternary polyammonium.

It is known to dye keratin fibers, for example human hair, with dyeing compositions comprising oxidation dye precursors, generally called “oxidation bases.” Representative oxidation bases include ortho- and para-phenylenediamines, ortho- and para-aminophenols, and heterocyclic bases.

Oxidation dye precursors are compounds initially only slightly colored or not colored that develop their dyeing power in the hair in the presence of oxidizing agents, leading to the formation of colored compounds. The formation of these colored compounds results either from oxidative condensation of the “oxidation bases” with themselves, or oxidative condensation of the “oxidation bases” with color-modifying compounds, or “couplers,” which are generally present in the dyeing compositions used in oxidation dyeing. Representative couplers include meta-phenylenediamines, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds.

The variety of compositions that can be employed in oxidation coloration, chosen from oxidation bases, oxidation couplers and mixtures of oxidation bases and couplers, can contribute to a pallet very rich in color.

The oxidizing agents which allow oxidative condensation generally may have an adverse effect on at least one property of the hair treated. The hair may become rough, difficult to disentangle and/or more fragile. To remedy at least one of the above-mentioned drawbacks, the use of certain quaternary polyammoniums has already been proposed in French patent 2,270,846, the disclosure of which is incorporated by reference herein.

However, the inventors have observed that the polymers mentioned above tended not to make it possible to sufficiently remedy at least one of the disadvantages while preserving or improving the dyeing properties.

The inventors have discovered that it is possible to obtain oxidation dyeing compositions with at least one improvement over previous dyeing compositions with respect to cosmetic properties. Additionally, such compositions may favor more intense and more chromatic (radiant) shades, while exhibiting low selectivities and good fastness toward chemical agents (shampoo, permanent waving and the like) and/or natural agents (light, perspiration and the like), and while offering the hair good cosmetic properties. The inventors have discovered that it is possible to obtain at least one of the aforementioned characteristics by formulating a cosmetic dyeing composition comprising (1) at least one oxidation dye, and (2) a combination comprising at least one cyclohomopolymer of dialkyldiallylammonium and at least one other particular quaternary polyammonium.

At least one of these discoveries forms the basis of the present invention.

The subject of the present invention is thus a cosmetic composition for oxidation dyeing keratin fibers, such as human keratin fibers like hair, comprising, in a dyeing medium (1) at least one oxidation dye, and (2) a combination comprising at least one cyclohomopolymer of dialkyldiallylammonium and at least one other particular quaternary polyammonium.

Another subject of the invention relates to a ready-to-use cosmetic composition for oxidation dyeing keratin fibers comprising, in a dyeing medium, (1) at least one oxidation dye, (2) a combination comprising at least one cyclohomopolymer of dialkyldiallylammonium and at least one other particular quaternary polyammonium, and (3) at least one oxidizing agent.
